Does anyone know how to do a Diffie-Hellman or ECDH key exchange with more than two parties?
I know how to do a key exchange between 2 parties, but I need to be able to have a key agreement between 3 ...

Is the Diffie-Hellman key exchange the same as RSA?
Diffie Hellman allows key exchange on a observed wire – but so can RSA.
Alice and Bob want to exchange a key – Big brother is watching everything.

In SSL protocols, both symmetric and asymmetric algorithms are used. Why is it so? The symmetric algorithms are more secure and easier to implement. Why are asymmetric algorithms usually preferred in ...

To give some foreground information: I acknowledge that I am a cryptography newb and not by any means an expert (and probably never will be).
In a recent CS class we had several assignments writing ...

The wiki defines the decisional Diffie–Hellman assumption as follows:
Decisional Diffie–Hellman assumption
Consider a (multiplicative) cyclic group $G$ of order $q$, and with generator $g$. The DDH ...

I've recently been looking at how to do perfect forward secrecy on a unidirectional connection (server can only push messages to client, client cannot respond).
What I've come up with is the idea of ...
